Answer:
The patients suffering from Guillain-Barre syndrome generally results in respiratory failure and diaphragmatic paralysis, therefore, the patient is kept on assisted ventilation. As mentioned the patient is kept on oral feedings through nasogastric true, and as the patient is respiring with the help of a tracheostomy tube, the threat of aspiration becomes high while doing oral feedings. However, this can be prohibited by closing the tracheostomy cuff by inflating it at the time of feedings in order to inhibit aspiration.
